BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent No. 715,997, dated December 16, 1902.

Application l'ed September 22,1902. Serial liloy 124,310. (No modeLi To all whom t may concern:

Be it known that I, SETH A. CRoNE, a citi-` zen of the Unit ed States, and a resident of New York, in the county of New York and State `of New York, have invented certain new and use-` crurn for the brake-lever; and my invention has for its object to produce a novel fulcruin for use in such beams, said fulcrum being efficient and capable of being firmly andv quickly applied to the beam.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a top view of a brake-beam constructed in accordance with and embodying the invention. Fig. 2 is a sectional View, on an enlarged scale, of a portion of the transverse center of same, this figure illustratingy the manner of utilizing one part or section of the fulcrum in clamping the other part or section of the fulcrum against the body-beam. Fig. 3 is a like view of same, this figure illustrating the parts of the fulcrum in position on the body-beam. Fig. 4 is an enlarged top view of the middle portion ofthe brake-beam. Fig. 5 is a detached perspective view of one part or section of the fulcrum. Fig. 6 is a detached side elevation of the middle portion of the brake-beam looking at the outer end of the fulcrum. Fig. 7 is an elevation looking at the outer end of one part or section of the fulcrnm, and Fig. 8 is a transverse section through a beam on a line denoted by the line 8 8 of Fig. 4 and illustrating a modified form of the invention.

In the drawings, 10 designates the bodybeam, 11 the usual brake-heads on the ends of said beam, and 12 the novel fulcrum of my invention, which is applied centrally on one edge of the beam 10,which will preferably be ofcommercialI shape.

The fulcrum 12 is composed of the sections or parts 13 14, which when in operative position close transversely around the flange 15 of the beam 10 and are secured to opposite faces of the web 16 of said beam by means of the rivet 17, the latter extending through the alined apertures 13 in said parts 13 14 and the aperture 19 in said web.

The part 13 of the fulcrum comprises a body portion consisting ofthe sections 20, 21, and 22 and the slotted lug 23,'between the sides of which the brake-lever (not shown) is to be mounted in the 'usual manner and which contain the apertures 24 to receive the usual bolt for sustaining said lever. The sections 20, 21, and 22 of the part 13 are adapted, respectively, to fit against the web and opposite faces of the flange 15 of the beam 10, the section 21 fitting against the inner face of said flange at one side of said web and the section 22 extending across the entire width of the outer face of said flange and having atits outer edge the rib 25, whose longitudinal center is preferably about on a line with the adjacent longitudinal edge of the ange 15, as shown in Figs. 2 and 3.

Thepart 14 ot' the fulcrurn 12 comprises the sections 26, 27, and 2S, the section 26 fitting against the web of the beam 10, the section 27 engaging the inner face of the iiauge 15 at one side of said web, and the section 23 being of hook shape and engaging the rib 25 ofthe fulcrum part 13. The part 14 performs two duties, one being to sustain the free or ribbed edge of the section 22 of the part 13 and the other being to bind, as by a cam action, said section 22 against the outer face of the flange 15. The hook-shaped section 28 of the fulcrum part 14 is closed at its opposite ends, as denoted at 29, whereby when the said part 14 is in position, as shown in Figs. 2and 3, the part 14 may not slide longitudinally of the rib 25 or of the body-beam 10.

In applying the fulcrum 12 to the beam 10 the fulcrum-section 13 will first be applied to the flange and web of said beam and have its rivet-aperture 18 placed in line with the aperture 19 through said web, as shown in Fig. 2, and thereupon the fulcrum-section 14 will IOO be applied, this section 14 being first hooked upon the rib 25 of the section 13, as shown in Fig. 2, and then pressed against the web of the beam 10 until it reaches a position in which it is shown in Fig. 3, with its rivet-aperture 18 in line with the aperture 19 through said web, whereupon the rivet 17 will be applied and headed in a known manner. An important feature of the invention is that when the section 14 of the fulcrum is moved from the position in which it is shown in Fig. 2 to the position in which it is illustrated in Fig. 3 it will draw against the rib 25 and bind the section 22 of the fulcrum part 13 against the face of the fiange 15 of the beam 10, the parts being so constructed and proportioned that this binding action shall take place by the pressing of the portion 2G of the fulcrum part 14 against the web ofthe beam 10, the purpose being that the part 14 of the fulcrum shall not only be enabled to support the section 22 of the Fulcrum part 13, but shall positively draw the same toward and bind the same against the fiange 15 of the beam 10. In the construction of the fulcrum part 14 the dimensions between the facing portions of the sections 27 and 28 thereof will be such as to enable the hooked portion 28 when the fulcrum part 14 is being applied to position to draw the section 22 of the fulcrum part 13 against the face of the iiange 15, and this binding action of the fulcrum part 14 may be enhanced when the central portion of the rib 25 is about on aline with the longitudinal edge, adjacent thereto, of the flange 15, as shown in Fig. 2. The fulcrum part 14 has no longitudinal sliding movement upon the rib 25, and hence after the fulcrum part 13 has been applied to position with its rivet-aperture 18 in line with the rivet-aperture 19 of the beam 10 the fulcrum part 14 may be quickly applied, with the assurance that its rivet-aperture 18 will necessarily pass into line with the said aperture 19. \Vhen the parts of the fulcrum are in position, as shown in Fig. 3, they are positively secured together and to the beam 10 by means of the rivet 17. The slotted lug 23 is not of unusual construction, and hence requires no special description, the present invention having to do more especially with the means hereinbefore described for securing said lug in proper position and condition to receive the usual brake-lever.

The fulcrum illustrated in Figs. 1 to 7, inclusive, is formed of the two parts or sections 13 14; but in Fig. 8 I illustrate a modified form of the invention in which 1 employ two of the clamping parts 14, each being iden tical with the part 14 shown in Fig. 2, the fulcrum shown in Fig. 8 being formed of three parts, the lug 23 and the two corresponding parts 14, for clamping the same against the face of the flange 15. The construction presented in Fig.

8 is presented simply to illustrate that the fulcrum may be made in three parts instead of two parts without departing from the invention so far as the same pertains to the clamping part 14 engaging the rib 25 of that part of the fulcrum carrying the lug 23, there being in Fig. 8 simply a duplication of the part 14 and rib 25.

What l claim as my invention, and desire to secure by Letters Patent, is

1. The body-beam having the brake-heads on its ends, combined with the fulcrum applied to said beam and comprising a part carrying the bearing-lug for the brakelever and having the edge rib 25, and the part 14 to be secured to the beam and having the hooked section 28 to engage said rib, said hooked seclion being provided with means to prevent it from sliding longitudinally on said rib, and said rib and hooked section being proportioned to enable said part 14 when being applied to position to exert a force against said rib and bind the part carrying the same against said beam; substantially as set forth.

2. The body-beam having the brake-heads on its ends, combined with the fulcrum applied to said beam and comprising a part applied against the ange of said beam and carrying the bearing for the brake-lever, and a part secured to said beam and in engagement with said bearing part, sai-d parts at their adjoining edges being respectively provided with the interlocking hook and rib so proportioned with respect to each other that during the application of said parts to the beam the said part carrying the said hook may have an axial motion over said rib and draw against and bind the rib part against the said beam; substantially as set forth.

3. The body-beam having the brake-heads on its ends, combined with the fulcrum applied to said beam and comprising the parts 13 and 14, the part 13 comprising the sections 20, 21, 22 fitting the outline of the beam, the bearing-lug 23 carried by the section 22 and the rib 25 on the said section 22, and the part 14 comprising the sections 26, 27 and 28, said sections 26 and 27 being adapted to engage said beam and said section 28 being hooked to engage said rib., and said parts being so proportioned that said hook may upon giving the part 14 an axial or turning motion to position on said rib eiect a positive force binding said section 22 against said beam; substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 19th day of September, A. D. 1902.
